Lung Function Improved with Use of Flavonoids

A type of flavonoid found in dark-pigmented fruits like red grapes and blueberries may slow the lung function decline that occurs with aging. Previous research has shown that the plant-produced chemicals known as flavonoids have beneficial antioxidant and anti-inflammatory properties. Anthocyanins, the type of flavonoid investigated in the current study, have been detected in lung tissue shortly after being ingested, and in animals models of chronic obstructive pulmonary disease (COPD). The plant chemicals appear to reduce mucus and inflammatory secretions.

Molecules Around The Cells Organizing Into Functional Structures

Researchers examined that the millions of molecules bumping around in a cell "find" one another and organize into functional structures. So it was a big surprise in 2008 when participants in the Marine Biological Laboratory (MBL) Physiology course realized that simple phase separations like oil separating from water may be one important way to create order inside a cell. The study was published in Science.

Potential of Quantum Dots Against Lung Cancer

Nanoparticles derived from tea leaves inhibit the growth of lung cancer cells, destroying up to 80% of them, new research has shown. The team made the discovery while they were testing out a new method of producing a type of nanoparticle called quantum dots. These are tiny particles which measure less than 10 nanometers. A human hair is 40,000 nanometers thick.

An Unusual Forms Of Proteins That Affect Gene Expression

Researchers examined that by turning genes on and off is an intricate process involving communication between many different types of proteins that interact with DNA. These communications can go awry, resulting in conditions like cancer. Researchers have uncovered an unusual form of cross-talk between proteins that affect gene expression, suggesting new ways of inhibiting metastasis in cancer.  The study was published in the Journal of Biological Chemistry.
